I just bought my first MD recorder, a Sony RH910 along with a Sony MS907 mic. I'll be recording my first concert with the MD next Friday, and I want to get a quality recording. In the past, I've always used my laptop and a mic, but that was only at gigs which I had permission to record. I bought the MD for stealth use. From what I have read on this site, my best route for good sound while staying out of sight, would be to build my own mics, affixed to glasses or my sleeves, and use a battery box. I have been into building tube guitar amps and guitar effects for years now, so I am sure I could rig up some decent devices. Only problem is, I am having a hard time finding some good mic capsules online. I search google and usually find whole microphones, not just the capsules. And the capsules I do find, I am not sure if they are what I need/quality parts (here are some from Mouser). Any recomendations as to what parts you all have had success with? Since I probably will not have my homebrew mics made in the next two weeks, any tips on using my MS907? I have ordered parts for a battery box from mouserelectronics and will be building it as soon as they arrive, and also plan on trying out the Radioshack headphone control. Hopefully I can find a show around here before next friday to see what setup works best. Sorry if this is a somewhat random post, I am just a MD newb and I want to get some good recordings from my new unit. Any help is appreciated
